Suitable alcohols are, for example, 2-butenyl alcohol; cinnamyl alcohol; 1-carboxy-3-hydroxy propene-l; 2- butene-1,4-diol; 3-hexene-2,5-diol; S-hexadecene-ZIO-diol; 1,4 cyclohexyl-2-butene-1,4-diol; 3,4-dihydroxy-2-butene; 3-hydroxycyclopentene-l; 3-hydroxycyclohexene-1, and

about four moles per mole are employed. A greater amount can be employed, if desired, for example up to ten moles per mole. A minimum of at least three moles of alcoholic component is employed per mole of bicyclic alcohol, but more usually a large excess, for example, up to 100 moles per mole, is employed to supply a solvent for the reaction. Other solvents can also be employed, such as inert diluents that do not participate in the reaction, but which are solvents for the bicyclic alcohol. Such diluents are dimethylsulfoxide, tertiary amines, such as N- methyl .morpholine, and the like.

In carrying out Reaction A, the reaction mixture is generally heated to about the reflux temperature, so that the temperature is somewhat dependent on the boiling point of the alcoholic medium. However, the reaction temperature is generally in the range of about 25 to 150 degrees centigrade. The reaction time can be varied over a considerable extent, but will generally be in the range of one to ten hours. At the completion of the reaction, the reaction mixture is acidified with a mineral acid, such as hydrochloric acid, and can be diluted with water, or if desired, these steps can be reversed. The reaction mixture is ordinarily filtered to remove inorganic salts, and any excess solvent can be removed from the reaction mixture by distillation. The product of the reaction can be purified by crystallization, washing, and drying or other suitable methods.

The products of Reaction A can be reacted with halogens and halogen halides to produce compounds wherein the hydrocarbyl, e.g., alkyl, cycloalkyl, alkenyl and aryl substituents as represented by X X X X R R R R and R are converted to the corresponding halogen-substituted radicals as represented by X X X X R R R R and R respectively. R represents the same radicals as R and, in addition, halogen-substituted alkyl and halogen-substituted cycloalkyl. The halogensubstituted alkyl, alkenyl, cycloalkyl and aryl radicals are as described hereinbefore.

In Reaction B, the tricyclic ketal product of Reaction A is-reacted with chlorine. The reaction is preferably carried out using chlorine gas as the reactant in the presence of a reaction solvent or diluent, such as a chlorocarbon, e.g., carbon tetrachloride, trichloroethane, trichloroethylene, perchloroethylene, and the like. The chlorination reaction can be carried out in the presence of ultraviolet light or with the aid of a peroxide catalyst, such as hydrogen peroxide or an organic peroxide, such as benzoyl peroxide, acetyl peroxide, butyryl peroxide, toluyl peroxide, cumyl peroxide, peracetic acid, perbenzoic acid, and the like. The catalyst can be added at the beginning of the reaction or in portions during the process. It can be introduced directly into the reaction mixture or together with the chlorine reactant. The quantity of catalyst is not critical since the reaction will proceed without the aid of a catalyst, but the preferred range of catalyst concentration is from about 0.1 to about 5 weight percent of the cyclic reactant. Reaction temperature is preferably in the range of about 3 0 to about 100 degrees centigrade, and the reaction time can vary from 2 to hours or longer periods of time.

Reaction C is generally carried out by suspending the tricyclic ketal product of Reaction A in a solution of a mineral acid, such as sulfuric acid, phosphoric acid, hydrogen bromide, hydrogen iodide, hydrochloric acid (in a miscible solvent such as acetic acid), and metal chlorides, such as aluminum chloride, zinc chloride, and the like. The concentrated acid solutions are preferably employed. At least about two moles of acid are used per mole of tricyclic ketal, but more usually a large excess, for example, up to 100 moles per mole is employed to provide a solvent for the reaction. An inert solvent or co-solvent can also be employed. The reaction temperature is generally in the range of 50 to 100 degrees centigrade, or up to the reflux temperature of the reaction mixture. The reaction is facilitated by agitation and the reaction time can vary from a few minutes up to five hours, but preferably is in the range of ten to sixty minutes, more preferably ten to thirty minutes. After the completion of the reaction, the

reaction mixture is cooled and filtered to recover the product. The resulting product can be purified by re- 6 crystallization, washing, drying, and other suitable methods.

In Reaction C, if the tricyclic ketal starting material has an R substituent that is hydroxyl-substituted (as produced in a series of reactions beginning with a bicyclic diol), somewhat milder reaction conditions are employed in accordance with the invention to inhibit the formation of a tricyclic ketone rather than the indicated product of Reaction C. Under these circumstances, the reaction temperature is maintained in the range of 50 to 100 degrees centigrade for ten to thirty minutes, and ten to fifteen minutes at to degrees centrigrade.

Reaction D is generally conducted by reacting the tricyclic hemi-ketal product of Reaction C with a phosphorus halide, such as phosphorus pentachloride or phosphorus pentabromide. At least about one mole of phosphorus halide is employed per mole of hemi-ketal, but an excess can be employed if desired, for example, up to ten moles per mole. A solvent can be employed for the process. The hemi-ketal compound starting material is mixed with the phosphorus pentahalide and heated slowly with agitation. The reaction is exothermic and evolves the hydrogen halide gas. After the initial mixing step, the reaction mixture is ordinarily heated at the reflux temperature, or generally in the temperature range of 100 to 15 0 degrees centigrade for a period of about one to five hours. The reaction product is hydrolyzed by contacting with at least one mole of water per mole of product, although a large excess of water is generally employed. Thereafter, the product can be purified by recrystallization, washing, drying, and other suitable methods. The bicyclic ketone product of Reaction D is disclosed and claimed in co-pending application S.N. 413,- 952, filed on even date herewith.

The 'bieyclic ketone product of Reaction D is capable of a number of reactions. Hence, the ketone product can be reacted with an alkoxide of the type described hereinbefore to reform the ketal product (Reaction G) which bears an R Z radical. Also, the bicyclic ketone can be reacted with an alkali metal bicarbonate, such as sodium bicarbonate, to form the hemi-ketal product having an hydroxyl radical (Reaction H). The latter reaction is preferably carried out by contacting a mixture of the bicyclic ketone, the desired alkali metal bicarbonate, water, and an alcohol diluent of the formula R ZH described hereinbefore. The mixture is heated, preferably at the reflux temperature, although temperatures in the range of 50 to degrees centigrade can be used. The reaction time can vary from as little as an hour up to ten to fifteen hours. After thecompletion of the reaction, the alcohol diluent can be removed by distillation, and the product can be purified by phase separation, Washing, drying, and other suitable methods.

In Reaction E, the bicyclic ketone product of Reaction D is contacted with an alkali metal cyanide, such as sodium cyanide, potassium cyanide, or the cyanides of the other alkali metals, e.g., lithium, rubidium, and cesium. At least one mole of cyanide is generally employed per mole of bicyclic ketone, but an excess, up to ten moles per mole can be employed. The reaction is generally carried out by adding the alkali metal cyanide to a solution of the bicyclic ketone starting material dissolved in an alcoholic compound of the formula R ZH described hereinbefore. The reaction mixture is heated to an elevated temperature, generally in the range of about 50 to 150 degrees centigrade, preferably at about the reflux temperature of the mixture, for a period of one to ten hours. The resulting reaction acid, hydrochloric acid, and the like. The reaction diluent can be removed by distillation, and the resulting product can be purified by crystallization, Washing, extraction, drying, and other suitable methods.

The reaction conditions set forth for Reaction E can also be employed with other nucleophilic reactants, such as alkali metal thiocyanates, e.g., potassium thiocyanate;

and alkali metal azides, e.g., sodium azide, to provide products having the corresponding nucleophilic radical attached to the bicyclic nucleus.

In Reaction F, the tricyclic nitrile product of Reaction E is reacted with a strong mineral acid, such as sulfuric acid, phosphoric acid, hydrobromic acid, hydroiodic acid, and hydrochloric acid; sulfonic acids, such as toluene sulfonic acid and alkyl sulfonic acids, and the like, to replace the CN radical with a carboxyl group. The reaction can be carried out in an organic solvent medium, such as acetic acid, formic acid, and similar inert media that are not reactive in the reaction system. The reaction involves hydrolysis. Therefore, at least one mole of water should be present per mole of cyano compound, and the reaction medium should be sufliciently acidic to cause attack of the cyano radical. The reaction mixture is generally heated to a temperature in the range of about 100 to about 150 degrees centigrade, preferably at about the reflux temperature of the mixture, and the reaction is continued for about two to about fifteen to twenty hours. The desired product can be removed from the reaction mixture by filtration, and can be purified by washing, drying, recrystallization, and other suitable methods.

The products of Reactions E and F and analogous reactions can be reacted with the halogens and halogen halides to produce compounds wherein the hydrocar-byl, e.g., alkyl, cycloalky, alkenyl and aryl substituents as presented by X X X X R R R R and R are converted to the corresponding halogen-substituted radicals as represented by X X X X R R R R and R respectively. The halogen-substituted alkyl, cycloalkyl, aryl and alkenyl radicals are as described hereinbefore.
